The fact that there are no time restrictions is great! Since I was using public transportation in an unfamiliar area and wasn't sure if it would run on schedule, it was helpful that I could enter anytime (within opening hours). The official booking site only allows reservations in 30-minute increments, which is stressful because you don't know if you'll be able to get in if you're late.
